<b>Abstract :</b><p align="justify">The use of microorganism in enhanced oil recovery or Microbial Enhanced Oil Recovery is not a new method , ZoBell , the first serious work on utilization of microorganism in oil recovery was done in early 1940's. <br /> <p align="justify">Naturally Microbial Enhanced Oil Recovery method utilizes the ability of bacteria to improve the quality of reservoir which also functions as a place of bacteria to grow, both are natural material that help increase the recovery . Reservoir is a combination of rock and fluid system . The reservoir performance is determined by the quality of material in the system itself The quality itself is characterized by the physical features of the rock and fluid as well as transmissibility. <br /> <p align="justify">Some of different species of microorganism have been isolated to determine morphology , their nutrient requirements, products of their metabolism and limit of environmental condition that can tolerate then four isolates have been succesfuliy isolated consist of four anaerobes - facultative - thermophylic bacterial isolate A2, A8, AS3 and AS5. <br /> <p align="justify">The quality of reservoir material can also characterized by porosity, permeability, wettability, oil viscousity, oil swelling , interfacial tension , saturation and heteroginity. <br /> <p align="justify">In this research , bacteria are expected to be produce bioproducts to improve the quality of material , so that it can achieve better the efficiency of microscopic displacement.
